EU members’ experience in tackling fraud and tax payment dodging

Organisation for Economic Co-operation and Development (OECD) has published a report describing EU members’ experiences in tackling fraud and tax payment dodging. In the report you can find information not only about the most common offences such as fraud and falsifying invoices but also about grey economy.
How should we tackle this? The first solution is to eliminate or limit cash transactions. Another proposal is to introduce electronic cash registers and to gratify people who inform the tax authorities about fraudulent activities within their companies. The Polish Ministry of Finance should make use of the experience of other countries in tackling the abovementioned issues.
